At the boot menu drop to the loader's command line (IIRC, option 6) and type:

set hw.ata.ata_dma=0
set hw.ata.atapi_dma=0
boot

Then continue with the installation.  If the installation completes
sucessfully, upon reboot remember to drop again to the command line menu of the
loader (so as to boot normally).  Then to have these changes permanet you can
place the at /boot/loader.conf.local as follows:

hw.ata.ata_dma=0
hw.ata.atapi_dma=0
